General Description

These are OBs for MOS spectroscopic observations of very high redshift
 candidates at z>6.5. The OBs consist of acquisition, through-slit positioning
 and of science exposures with small offsets along the slits. 

The high redshift targets are in the slitlets #5-#8, and we hope to detect their
 LyAlpha emission line. However, they are too faint for a detection of their continuum.
We assigned a total of 4 relatively bright stars (i_AB = 18.4 - 20.5) for the through-slit
 positioning. These are namely positioned in the slitlets #3, #4, #9, and #14. The
 through-slit images should be aligned to center these objects only.

In order to increase the possibility for scheduling our observations, we lessened
 the seeing constraint to 0.8".
